LOOSE-LEAF BINDE SPECIFICATION forming part of Letters Patent No. 682,851, dated geptember 17, 1901.

Application filed January 28,1901. Serial No. 1 1- (N0 model.)

My invention relates particularly to looseleaf binders wherein are employed posts for receiving the leaves,the leaves being provided with perforations at their rear margins.

My object is to provide a binder of this nature of improved construction, particular attention being paid to the provision of a readily-removable top clamping-bar and coversection for the binder.

My invention is illustrated in its preferred form in the accompanying drawings, in Which Figure 1 is a view in perspective showing the binder in use; Fig. 2, a broken horizontal section illustrating the upper clamping-bar, the device for clamping the same to the binding-posts, and the means for actuating said device; Fig.3, a similar View, but showing the movable slide employed for engaging the binding-posts in its locking position; Figs. 4. and 5, broken vertical sections taken as indicated at the corresponding lines of Fig. 2;

Fig. 6, a perspective view illustrating the clamping-bars and the locking device for the upper clamping-bar, the parts being separated from each other; and Fig. 7, an enlarged broken plan view of the movable slide or locking-bar employed.

A represents the lower cover-section; A, the lower clamping-bar; A binding-posts projecting upwardly from the bar A; B, the

upper cover-section 5v B, the upper clam ping-' bar, and B a locking device connected with the upper clamping-bar.

The device B comprises a bar a, provided with headed studs a, an operating-lever a provided with cam-shoulders a and a and a sliding bar I), provided with a rectangular cam-receiving recess b and curved post-receiving recesses b b The portions of the recesses b b which extend longitudinally of the slide-bar I) receive the studs a, and the heads of said studs serve to prevent separation of the slide from its companion bar, as

clearly shown in Fig. 4. The upper Lim ing-bar B is provided at its rear edge with fl post-receiving recesses c, and the member-a of the device 13 is provided at its rear edge with post-receiving recesses c. In practice the bar B is covered with cloth djas shown in Fig. 5, and the cloth is provided with slots d, corresponding with the slots 0. The member Ct of the device 13 is secured to the upper 6o clamping-bar at points f, as shown in Fig. 1. The slots b b comprise channels. 9, perpendicular to the rear edge of the bar b, and offset channels g, extending in the same direction from the channels g. This is most clearly illustrated by Fig. 7, from which it appears that the channel 9 is reduced somewhat in width near its junction with the channel g, thereby afiording a locking-shoulder g whichshoulder springs past the center of the 79 adjacent post when the parts are brought to a locking position.

From the foregoing description and from a View of Figs. 2 and 3 it will be readily understood that when the lever a is in the po- 7 5 sition shown in Fig. 2 the shoulders g are out of engagement with the binding-postsand the channels g are in registration with the slots 0 a. With this position of the parts spring past the centers of the binding-posts.

It is readily seen that the shoulder a of the lever a serves to engage one lateral wall of the slot b to move the slidein one direction, and the shoulder a serves toen gage the other lateral wall of said slot to move the slide in the opposite direction.

It is evident that a great advantage is derived from having the upper clamping-bar provided at its rear edge with slots, permitting the attachment in the manner shown 5 and described, thereby rendering it unnecessary to move the clamping-bar to the top of the posts when it is desired to take a sheet from the file, and it is also evident that it is an advantage of construction to have the member b of the locking device formed with the channel g and the channel 9' branching therefrom the cover-section B may be drawn forward 80 in the same direction, whereby the movement of the member I) in one direction serves to efiect a disengagement at both bindingposts, and movement thereof in the other direction serves to eifect a looking at both binding-posts.

Changes in details of construction within the spirit of my invention may be made, and therefore no limitation is intended by the foregoing detailed description, except as snall appear from the appended claims.

What I claim as new, and Zesire to secure by Letters Patent, is.-'

1. In a loose-leai'blnuer, alower clampingbar having upwardly-projecting posts, an upper clamping-oar provided at its rear edge with lots receiving said posts, a slide pro JidBC1 with shoulders for engaging said posts,

movement of said slide in one direction serving to effect a locking and movement of said slide in the opposite direction serving to effect an unlocking, and means for actuating said slide, substantially as described.

2. In a loose-leaf binder having upwardlyprojecting posts, an upper clamping-bar having at its rear edge slots for receiving said posts, headed studs above said upper clamping-bar rigidly connected therewith, a slide having slots registrable with said first-named slots for receiving said studs and shoulders for engaging said binding-posts, and means for actuating said slide, substantially as described.

3. In a loose-leaf binder, a lower clamping: bar having upwardly extending bindingposts, an upper clamping-bar having post-receiving slots at its rear edge, and a locking device for the upper clamping-bar comprising a member a rigidly connected with the upper clamping-bar and provided at its rear edge with post-receiving slots, a slide having longitudinal movement with relation to said member 01, and provided with slots registrable with said first-named slots and with shoulders for engaging said binding-posts and an actuatinglever connected with the member a and serving to move said slide, substantially as described.

&. In a loose-leaf binder, a member a provided with post-receiving slots, a member I) provided with post-receiving slots, post-em gaging shoulders and a cam-receiving recess, and a cam-lever a pivoted to the member at and provided with cam-shoulders a a, substantially as described.

5. In a loose-leaf binder, an upper clamp= ing-bar provided at its rear edge with postreceiving recesses, a slide connected with said bar and provided with recesses g having ofisets g afiording shoulders 9 and means for actuating said slide, substantially as de= scribed.
